The Short Version
This claim is well-supported by strong scientific evidence. A 2025 randomized controlled trial found that a 10-minute post-meal walk significantly lowered peak blood glucose (164.3 vs. 181.9 mg/dL, p=0.028) compared to remaining sedentary. A 2023 systematic review with meta-analysis confirmed across 15 effect sizes that post-meal exercise reduces postprandial glucose versus inactive controls, especially within 0–29 minutes of eating. Multiple additional studies and clinical sources corroborate this finding.
